DRAIN-COCK FOR MOTOR-VEHICLE CASES.

Specification of Letters atent.

Patented Nov. 17, 1903.

To all whom it may concern:

Be itlinown that I, RUSSELL Herr, acitizen of the United States, andresident of Detroit, Wayne county, State of Michigan, have inventedcertain new and useful Improvements in Drain-Cocks for Motor-VehieleCases, of which the following is a speciiication:

The present inveiitioirrelates tov improveineiits in drain cocks andparticularly 'to such devices as are employed on niotor Vehicles.

in a niotor vehicle the drain eoeks i'roni the crank and gear eases andother parts, are necessarily so located as to be exposed vto inud anddust thrown by the wheels WhenA the vehicle is in motion and the outletsthereoi" quickly becoine so clogged that it is iinpossible for fluid topass until they have been cleaned by a wire or other ineans.

rihe object oi' the present invention is to provide a drain cook theoutlet of which will not becoiiie thus clogged and which can be openedat aiiy tiine by simply turning the plue'.

The invention is illustrated in the aecompanying drawing in which,

Figure 1 is a longitudinal sectional View through a drain eorltconstructed in accord'- nnce with the present invention showing the plugin closed position; Fig. 2 is a similar view, the plug being turned toopen the passage through the cock; Fig. 3 illustrates the plugl andparts connected therewith detached troni the body oiu the cock.

Referring to the drawings, it .will bei seen that the eocli comprises abody l liav; ng a suitable passage therethrough and provided at one endwith a threaded section 2 by means ot which it may be secured in asuitable threaded passage. Ataii intermediate point in its length thebody l is suitably enlarged and provided with a transverse passagethrough which extends a tapered plug 3 having therein a passage 4 whichas the plug is turned Will aline with the passage through the oook, topermit lfluid ,to iiow therethrough. TWhen the plug is turned to theposition shown in Fig. l, the passagetherein is out of aliiieinent withthe passafre in the cock. oi" Jdie plug is inthe closed position.

from a single lilanr: s..

proper relati angles to the length et the plug, and the smaller end ofthe plug extends beyond the body l, being reduced in size, and, asshown,

preferably inade polygonal in Cross section.

When the plug is in its closed position the out-let of the passagethrough the cool( is closed by a guard or shield 6 which, as shown, ismounted upon the polygonal shaped section oi' the plug so as to turntherewith. This shield is held elose against the body of the Coeli by a.spring 8 which isI compressed between said shield and a Washer 9 securedto the projecting portion of the plug by a Cotter key l0.

The surface ot the body l of the noch siiirounding the outlet openingthere' i made tlat and the guard or shield is of suoli torni and sorelated to the plug that when the latter is in its closed position theplate like portion 811 of said guard will eontaet closely with the i'iatsurface on the. eoek and thus 'act to held ihe plug in its closedposition.

As shown the shield or vruard G is inade y ine al bent intosubstantially right angled 'torni and having at one end a polygonalaperture eoniiorinine in cross sect-ion te the shape of the section erthe plug which .extends tl erethrough, the free endet said guard beinge. a. into a plate like section if which as above described is adaptedto closely Contact, wit-li the ilat surface about the outlet to theooelt and eteetually prevent the entranee intothe passage of the Coeliv-rhen ilierein is in its Closed position. v

Having thus deseribedtlie intention what is claimed and desired to besecured hy 1. ters-Patent is, v

l. The Combina-tion with a drain coal( for motor-vehicles, having a,body and plug, et a guard havingone end `ooiiiieeted 'with a. portionol? the plug' and having its free end adapted to extend across theoutletwlien the plug is in Closed position, and spring surrounding theplus' id holding" the parts ii i with a drain @oehr tor motor vehicles.,et a guard having one end IGC
